# What is value of money? ###### 2008-08-26 11:00:56

The time value of money is based on the premise that an investor prefers to receive a payment of a fixed amount of money today, rather than an equal amount in the future, all else being equal. In particular, if one received the payment today, one can then earn interest on the money until that specified future date. All of the standard calculations are based on the most basic formula, the present value of a future sum, "discounted" to the present. For example, a sum of FV to be received in one year is discounted (at the appropriate rate of r) to give a sum of PV at present. Some standard calculations based on the time value of money are: : Present Value (PV) of an amount that will be received in the future. : Present Value of a Annuity (PVA) is the present value of a stream of (equally-sized) future payments, such as a mortgage. : Present Value of a Perpetuity is the value of a regular stream of payments that lasts "forever", or at least indefinitely. : Future Value (FV) of an amount invested (such as in a deposit account) now at a given rate of interest. : Future Value of an Annuity (FVA) is the future value of a stream of payments (annuity), assuming the payments are invested at a given rate of interest.
